LUBRICATING DEVICE.

Application filed February 7, 1916.

To all whom it may concern:

Be it known that we, SAMUEL E. LAW- RENCE and GEORGE M. DAVIS, citizens of the United States, residing at West Point, in the county of Hardin and State of Kentucky, have invented new and useful Tm provements in Lubricating Devices, of which the following is a specification.

This invention relates to lubricating devices, and it has particular reference to devices for lubricating the inside of steam and gas cylinders whil in active use; also for lubricating the valves, packing and rods or stems of the engine on which it is placed.

The invention has for its object to produce a lubricant container of very simple construction, free from valves and the like requiring attention and regulation and adapted to be used as a container for lubricating material in cartridge form only.

A further object of the invention is to produce a lubricating device consisting of a container adapted to receive a charge of lubricating material in cartridge form, said container having a readily removable cover and a nipple which is externallythreaded to engage the cylinder wall, cylinder head, valve casing or other part of an engine to be lubricated where the lubricant container will be subject tothe admission and exhaust of motive fluid in a heated state.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however,understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawing, Figure 1 is a view in side elevation of the lubricant container. Fig. 2 is a vertical sectional view showing the container applied to a cylinder head in position for operation. Fig. 8 is a perspective view showing a cartridge of lubricating material adapted to be used in connection with the device.

Corresponding parts in the several figures are denoted by like characters of reference.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Serial No. 76,802.

The lubricant receptacle or container 15 is preferably of hexagonal or other noncircular cross section externally, as seen in Fig. 1, and it has at one end a nipple 16 which is externally threaded. as shown, said nipple communicating with the interior of the receptacle which preferably consists of a cylindrical bore 17, the same being internally threaded at its upper end for the reception of a tightly fitting cap 18 having an overhanging flange 18 whereby the longitudinal movement of the cap within and relatively to the receptacle is limited. The nipple 16 engages a threaded aperture 19 which is formed in the cylinder head 20 or other object to which the lubricant receptacle is to be applied, the non-circular contour of the receptacle enabling a wrench of ordinary construction to be utilized for the purpose of securely tightening the said receptacle in position for use.

The lubricant supplied to the receptacle is in the form of a cartridge 21 of cylindrical form, the same being composed of a plastic mass, said mass consisting of a compound of graphite in flake or powdered form, the same being mixed with other perfect lubricant-s to form a cohesive mass of a consistency that will permit it to be made into cartridges of convenient form and dimensions. No limitation is made to any particular formula for the lubricant beyond that it is preferably composed of graphite and a binding medium which in itself constitutes a perfect lubricant and which is capable of being reduced by heat to a proper state of fluidity.

In operation, the container is applied in some proper location to the cylinder or valve chest of the engine which is to be internally lubricated. A cartridge of the lubricant is then placed in the container to which the lid or cover is tightly applied. It is to be understood that the parts of the de vice are to be strongly made and provided with perfectly tight joints, inasmuch as the interior will be subjected to the pressure of the steam. When the engine is in operation the steam or gas entering the lubricant container through the nipple will reduce a portion of the cartridge to a sufficiently fluid condition to enable it to be drawn through the nipple when steam is exhausted from the portion of the cylinder or valve chest with which the device is connected. The operation of the lubricating device will continue automatically as long as the engine is in operation. When the operation of the engine ceases the feed of the lubricating materialis automatically cut ofl", and such portion of the cartridge as may have been melt ed may be permitted to congeal until the engine is again started. The overhanging flange 18 of the cap 18, by limiting the longitudinal movement of said cap within and relatively to the lubricant receptacle prevents the cartridge from being crushed or forciby driven through the bore of the nipple 16 which constitutes the feed channel, said bore being designated by The improved lubricating device will replace sight feed lubricators and valved lubricating systems such as are now employed for the purpose of internally lubricating cylinders, valve chests and the like. The improved device requires no attention whatever beyond that of being supplied from time to time with a fresh cartridge of lubricating material. It is simple and inexpensive in construction, easily installed and thoroughly efficient for the purposes for which it is provided.

Having thus described the invention, what is claimed as new, is

The combination with a part of an engine in which during operation pulsation of steam or other motive fluid in a heated state takes place, of a lubricant receptacle having a nipple whereby it is fixedly connected with such engine part and having a reduced bore communicating therewith, and a cartridge of congealed lubricating material in such receptacle whereby by the-pulsation of the motive fluid said fluid will enter the receptacle, reduce a portion of the cartridge to a fluid condition and cause such fluid portion to be drawn through the nipple when the motive fluid is exhausted from the portion of the engine part with which the device is connected.

In testimony whereof we aiflx our signatures in presence of two witnesses;

SAMUEL E. LAWRENCE. GEORGE M. DAVIS.
